Title: Boiling water reactor
Inventor: NAKAJIMA YOSHITAKA
IPC: G21C15/16
Filed: 1991-01-31
Abstract: PURPOSE:To improve a vapor-liquid separation efficiency in a vapor-water separator and a natural circulation drive of a coolant by disposing a plurality of chimneys which make the opening of an outlet of a channel box of a fuel assembly communicate with the inlet side of the vapor-water separator. CONSTITUTION:A vapor stream produced by boiling in a channel box 23 of a fuel assembly 12 is guided into a chimney 25 from the upper opening of the box 23, passed through the chimney 25 and guided into a vapor-water separator 17 from an opening in the upper end thereof. Since this vapor stream is guided smoothly without mixing with subcool water when it passes through an upper plenum part 16, the flow rate of vapor guided to the separator 17 increases and a vapor-water separation efficiency is improved. On the occasion, a pressure loss of the separator 17 can be made small, since no subcool water mixes in the amount of a coolant. Since no vapor-water mixing occurs on the outlet side of the box 23 either, on the other hand, the pressure loss of the coolant in the plenum part 16 can be lessened and, besides, a head pressure can be maintained sufficiently. Thereby the force of a natural circulation drive of the coolant can be improved.

Title: Pressure control valve
Inventor: YAHARA SHIGEO
IPC: F16K17/30
Filed: 1982-01-27
Abstract: PURPOSE:To surely shut off the passage of fluid by a structure wherein two valves are provided in the passage locating between a primary side and a secondary side. CONSTITUTION:When the pressure in a secondary side reaches a predetermined value, the center part of a diaphragm 6 locates itself at the position, at which the pressure in secondary side balances with the strength of a pressure control spring 4, and realizes the normal state that the first valve is kept open and the second valve is closed. At this time, the lower end 7'' of a spindle 7 and the upper end 11'' of a spindle 11 contact with each other at all times and the spindles 7 and 11 act as one body and only the second valve opens and closes at all times in association with the actuation of the diaphragm 7 accompanied by the pressure variation in the secondary side. If the pressure in the secondary  side slightly exceeds said predetermined value, the center part of the diaphragm  6 is pushed up, resulting in raising the spindle 7 in order to close the first valve so as not to allow the pressure in the secondary side to exceed the predetermined value to a large extent. Subsequently, the first valve is opened and closed  in response to the pressure variation in the secondary side.

Title: Method of washing pressure vessel of nuclear reactor and internal structure and device therefor
Inventor: KUROSAWA KOICHI
IPC: G21F9/28
Filed: 1995-01-27
Abstract: PURPOSE: To effectively wash the inner surface of a pressure vessel of a nuclear reactor and internal structure with reactor water held by using impact pressure when cavitation bubbles generated by a high speed water flow jetted from a nozzle moving parallel to a surface to be washed are collapsed to perform washing. CONSTITUTION: A washer 100 is fixed to the center of a pressure vessel 1 of a nuclear reactor, and a turning and elevating/lowering driver 24 is driven by a control panel 17. Thus, a nozzle holding arm 4 performs turning and elevating/lowering movement with respect to a main column 81. At the same time, high pressure water is fed into a high pressure hose 14 and jetted from a nozzle 5. Therefore, while the nozzle 5 moves vertically and turns to the wall surface of the nuclear reactor pressure vessel 1, it jets high pressure water. In this way, cavitation is caused in reactor water 3 by the high pressure water. By this cavitation, bubbles are generated, and the bubbles collide with the inner wall surface of the vessel 1 and are collapsed. By impact pressure at this time, radioactive scale stuck on the surface is removed.  As a result, the increase in radiation dose rate due to the lowering of the reactor water level is prevented, and thus the radiation exposure of workers is reduced.

Title: Vapor phase growth method
Inventor: ICHIKAWA MICHIO
IPC: C23C16/458
Filed: 1982-01-29
Abstract: PURPOSE:To prevent the generation of any mound and auto-doping, by effecting a vapor phase growth while maintaining the wafer surface downward. CONSTITUTION:A wafer support device 1 has a bottom plate 2 and a pair of side walls 3 stood upright on both sides of the bottom plate 2. A hollow top panel 5 supporting a susceptor 4 suspended therefrom is mounted between the side walls 3. The susceptor 4 has a wafer-holding recess 4a opened downwardly. Suction-holding bores communicating with a suction duct 5a are opened in the bottom surface of the recess 4a, i.e., a wafer-holding surface 4b. A tunnel-like space S is defined between the rear surface of the susceptor 4 and the upper surface of the bottom plate 2 so that a growth gas flows through the space S in the direction of an arror f1. If a vapor growth is carried out by such an apparatus 1 while a wafer is being supported thereby, since the wafer surface is directed downward, the adhesion of minute dust is prevented to make it possible to obtain an extraordinarily high mound-free rate. In addition, it is possible to suppress the auto-doping caused by the growth gas passing around to the reverse surface of the wafer.

Title: Method for adjusting period of triangular wave
Inventor: KONO AKIO
IPC: G01F1/66
Filed: 1998-01-26
Abstract: PROBLEM TO BE SOLVED: To enable a highly accurate ultrasonic measurement of flow velocity regardless of environments, by repeating the adjustments of periods of triangular waves once or a plurality of times, and converging periods of triangular waves to reference periods of triangular waves. SOLUTION: Triangular waves P whose periods have been changed by temperature are outputted from a triangular wave generating circuit 6. The voltage value of the triangular waves P at a reference time is held by a holding circuit 11 and is converted into digital form by an AC converting circuit 8, and the converted voltage value is transmitted to a microcomputer 15. The microcomputer 15 calculates a difference between resistance values by a correcting expression and transmits it to the triangular wave generating circuit 6. The circuit 6 automatically performs the operation of lowering the pre-correction resistance value of a variable resistor by the difference between resistance values and matches triangular waves to output to reference triangular waves Q.  In this way, it is possible to perform convergence that makes coincide or approximates the triangular waves P whose periods are changed by temperature, etc., to the reference triangular waves Q with constant periods only by one adjustment. As stable triangular waves are outputted from the triangular wave generating circuit 6 at all times as a result of this, it is possible to make invariable the time required for triangle waves to reach a constant voltage, and further to perform highly accurate ultrasonic measurement of flow velocity regardless of environments.

Title: Device for measuring gap of blade tip
Inventor: HATTORI TOSHIO
IPC: G01B11/14
Filed: 1990-01-24
Abstract: PURPOSE:To measure the fluctuation in the gap of a blade and the amount of blade vibration by making a laser beam obliquely incident on a blade tip and measuring deviation at the detection position of a reflected beam. CONSTITUTION:When a laser beam 5 is made incident from the outside of a casing 3 to a tip surface 9 of a moving blade 2 in an initial state, a point A of an optical sensor surface 7 is irradiated with a reflected beam 6. Next, when a rotor under working and the casing are deformed and the blade tip is moved to a position 9', the point irradiated with the reflected beam 6 is moved to a point B. According to an amount DELTA of this movement from the point A to the point B, fluctuation amount DELTAdelta in the gap of the moving blade tip is calculated. Further, by setting the beam 5 so that the projection line of the incident beam 5 to a tip surface 9 can be orthogonal to a vibrating direction 10 of the blade, the inclination of the tip surface 9 caused by the vibration of the blade can be detected as movement (d) of the irradiated point between points C and D.
